It can surely be a reason for a vibration failure if the module isn’t mounted flush with the board and can actually moved by hand. Copper is horrible when repeatedly flexed.
I’d suggest strain relief of the assembly with some elastic compound to the board, if possible. It’s also important to evaluate if the module is ‘top heavy’, since the regulator body will leverage to the board.

Le chargement sans fil est si pratique pour l’utilisateur car il ne nécessite aucun fil, mais ce n'est pas aussi populaire que le marché. Il doit y avoir des raisons du côté du fournisseur, n'est-ce pas?
Afin de réduire la taille d'un PCB, Je devrai probablement utiliser des composants SM plus petits. J'utilise actuellement principalement 0805 passifs, et je pense y aller 0402 ou plus petit. Outre les considérations de dissipation de puissance, les pièges dont je devrais être conscient lors de la transition?
Je m'occupe d'un projet concernant un PCB avec antenne NFC. Nous concevons des PCB maintenant. Quelqu'un connaît-il la taille d'une antenne NFC si nous voulons qu'elle fonctionne 10 centimètres?
